HOOD-FASTENER.

Specification of Letters Patent.

Patented Dec. 20, 1921.

Application filed November 10, 1920. Serial No. 423,065.

To all whom it may concern:

Be it known that I, CARL R. HENNIOKE, a resident of Buffalo, in the county of Erie and State of New York, have invented a new and useful Improvement in Hood-Fasteners, of which the following is a full, clear, and exact description.

The present invention relates broadly to fasteners and more particularly to barrel fasteners of the type adapted for use on automobile hoods; An important object of the present invention is to provide a fastener of the type described in which relative rotational movement is permitted between the portion connected to the hood andthe portion connected to the automobile frame or chassis.

Another object of the invention is to provide a fastener of the barrel type, in which the upper portion of the barrel is closed to prevent the entrance of foreign matter, and in which one of the fastening devices forms a partial closure for the normally open lower end of the barrel.

A further object is to provide a spring fastener having a combined sliding, swingin and camming movement with means for ad uSting the tension of the spring.

A still further object of the invention is to provide a fastener having a removable yoke adjustably carried by the spring-controlled piston within the barrel or casing.

The foregoing and other objects, together with their attendant advantages, will be apparent as the invention becomes better understood by reference to the accompanying specification and drawings forming a part thereof, it being promised, however, that changes may be made in the various details and the manner of operation within the scope of the appended claims, without departing from the spirit of my invention.

Figure l is a front elevation of a fastener in osition on a hood; and

ig. 2 is a vertical section on the line II-II of Fig. 1.

Referring more particularly to the drawings, there is indicated a portion of an automobile hood 2, having its lower edge adjacent the frame or chassis 3. Secured in any desired manner to the frame or chassis 3 is a fastening plate 4, having a projecting bearing portion 5, provided with a suitable opening for the reception of a pintle 6. Co operating with the bearing portion 5 is a barrel 7 having a closed upper end 8, and a normally open lower end 9, from the opposite sides of which lugs 10 project downwardly to receive the pintle 6. With the fastening plate and barrel in the position illustrated in the drawings, it will be apparent that the bearing 5 forms'a partial closure for the normally open end of the barrel, thereby preventing the accidental loss of any of the parts contained within the barrel.

Mounted within the the barrel for rotational and longitudinal movement is a piston 11', having an enlarged head 12, adapted to compress a spring 13, between the same and the upper end of the barrel. The piston 11 has its upper end threaded to adjustably receive a yoke 14, between the sides of which is pivotally mounted a cam 15, having an operating handle 16 of any desired construction.

Secured to the hood 2 is a plate 17 carrying a post 18 adapted to project between the sides of the yoke 14, and provided with a cam-shaped upper face 19, adapted to cooperate with thecam 15. For limiting the backward movement of the handle 16 be yond a predetermined point, the cam is provided with a projection 20, adapted to engage the post 18 and definitely stop the same.

In operation of the device, after the plates 4 and 17 have been secured in their respective positions, it will be apparent that by grasping the handle 16 and swinging the same forwardly, the piston will slide within the barrel 7 against the action of the spring and permit the cam 15 to be disengaged from the post 18. In securing the fastener in position, the reverse operation takes place. The desired tension on the spring 13 may be maintained at all times by adjusting the position of the yoke on the piston.

The advantages of the present invention arise from the provision of a construction in which relative rotational movement is permitted between the different parts of the fastener to accommodate the movements of the hood under tractive influences, and in which the tension on the spring device ma be varied to suit the conditions encountered: Further advantages arise from the means for limiting the backward movement of the operating handle and for preventing loss of the parts of the barrel I claim:

1. A fastener of the character described,

comprising a barrel having a lower open end provided with oppositely disposed downwardly projecting lugs, a fastening plate adapted to cooperate with said ln s to form a pivotal mounting for said barre and partially close said lower open end, a springpressed piston rotatably supported within said barrel, said piston being engageable through the lower open end of the barrel to hold the same against rotation during assembly of the parts, a yoke on said piston, a cam pivotally supported in said yoke, and a post having a cam-shaped face adapted to receive said cam, substantially as described.

2. A hood fastener of the character described, comprising a barrel provided with oppositely disposed downwardly projecting lugs, a fastening plate adapted to cooperate with said lugs toform a pivotal mounting for said'barrel, a spring pressed piston rotatably supported within said barrel,'a yoke on said piston, a cam pivotally supported in said yoke, a post having a cam shaped face adapted to receive said cam, a handle for operating said cam, and a stop cooperating with said post for limiting the movement of said handle in one direction to maintain the handle and barrel out of contact with the hood, substantially as described.

3. A fastener of the character described, comprising a barrel having a lower open end provided with oppositely disposed downwardly projecting lugs, offset with respect to the longitudinal axis of the barrel, a fastening plate adapted to cooperate with said lugs to form a pivotal mounting for said barrel and artially close said lower open end thereof, a spring-pressed piston for said barrel, a yoke adjustably mounted on said piston, said piston being engageable through the lower open end of said barrel when theparts are in operative position to permit adjustment of the yoke, a cam pivotally supported in said yoke, and a post havmg a cam-shaped face adapted to receive 'said cam, substantially as described.

In testimony whereof, I have hereunto set m hand.

y CARL R. HENNICKE.
